CompTIA SecurityX (CAS-005)Security EngineeringMedium
A security architect is designing a key management system for a global enterprise that processes highly sensitive customer data. The system must ensure that cryptographic keys are generated, stored, and managed in a tamper-resistant environment, meeting stringent regulatory compliance requirements (e.g., FIPS 140-3 Level 3). Which specialized hardware component is BEST suited for this purpose?
- AField-Programmable Gate Array (FPGA)
- BTrusted Platform Module (TPM)
- CHardware Security Module (HSM)
- DSecure Element (SE)
Show answer & explanationAnswer & explanation
Correct answer: C. Hardware Security Module (HSM)
A Hardware Security Module (HSM) is specifically designed to perform cryptographic operations and securely store cryptographic keys in a tamper-resistant and tamper-evident hardware device, meeting high-level compliance standards like FIPS 140-3 Level 3.
Why the other options are wrong
- A. FPGAs are reconfigurable integrated circuits, used for custom hardware acceleration, not primarily for secure key management or FIPS compliance.
- B. TPMs provide secure boot and limited cryptographic functions, but are generally not designed for the enterprise-grade key management and high FIPS levels required here.
- D. Secure Elements are typically found in mobile devices or smart cards for securing small amounts of sensitive data, not for enterprise-wide key management.
Hardware Security Module (HSM)
A physical computing device that safeguards and manages digital keys, performs cryptographic functions, and provides strong authentication within a tamper-resistant hardware environment.
- Provides tamper-resistance and tamper-evidence
- Generates, stores, and protects cryptographic keys
- Supports high FIPS 140-3 levels for regulatory compliance
